UNITED STATES PATENT OFFICE FREDERICK KLEIN, OF COLLEGE POINT, NEW YORK,ASSIGNOR TO SEEP-EASTWOOD CORPORATION, OF' IPAT ERSON, NEW JERSEY, ACORPORATION OF NEW JERSEY Applicatlon filed March 27, 1981. Serial No.525,801.

This invention relates to creelsfor supporting wound yarn packages fromwhich yarns are drawn, as in the operation of'preparing a warp, andparticularly to that class of creels in which there is provision forshifting any package from its normal yarn delivering position to aposition convenient to the operator for substituting an exhaustedpackage by a fresh one. One object of the invention is to construct thecreel so as to accommodate as many packages in a given area as possibleand yet allow the shifting of any package to the position for doflingand substituting a fresh one,with ample c earance for that purpose.Another object is to construct a creel so as to simplify thesame andreduce the cost of manufacture and of assembling its various parts andpermit the ready placement of the elements of each unit involved in thedelivery I of the yarn and its tensioning. or guidingmeans in differentelevations on the frame or main supporting structure in any arrangementdesired or required by the number of such units to be resent.

I attain my rst object by packages in groups of two and mounting eachtwo packages on carriers which are pivotedon substantially parallel axesand, when the packages are in working or delivering position, lap (ascross) each other between their packages and their pivots..

I attain my second ob ect by constructing each yarn supply (which I heremean 'to include, with yarn tensioning or other guiding means, means tosupport the latter and also a yarn package with the axis of the lattersubstantially alined with said means) as a unitary structuregattachedtothe frame, being preferably adapted to assume various posi-.

arranging the ply with the wound package shown in broken outline. g

Figs. Z and'8 are a side elevation and plan showing ,wound packages .inthe form of spools insteadof cones; and c Fig. 9 shows a modification. 4

Any suitable frame may be used. In the present example it is shown asincluding two upright converging rid-like structure's each i comprisinga lower orizo'ntal rail 1, a top horizontal rail 2 and bars or uprights(as pipes or tubes) 3 rigidly connecting them, on y a fragment of onetop rail appearing on Fig. 1. The ends of the structures ,may beconnected by braces 4 (only the bottomone at the wider end of thecreelbeing shown) and atthe wider end of the creel there may be a reed 5 orequivalent means for keeping separated those yarns which lie all in thesame horizontal plane.

Each yarn supply here includesv a bracket,

a wound package carrier -(in the preferred form two such carriers)mounted therein and atension (or guiding) means. It is attached to oneof the uprights 3 as a unit and is capable of adjustment up or downthereon as such, as will appear.

The bracket includes a body part 6 and an arm 7 projecting rigidly andforwardly therefrom. The body part is adapted to bear against one of theuprights 3 and for this purpose it has a rear groove 8 to receive thesame.- It forms one member'of a clamp the other member of which isa-U-shaped clip9 which embraces the upright andhas its ends threaded andpe'netratingthe' body part and provided with clamping nuts 10. At thetopit has an upstanding horizontal frontal ledge 11 to guide loose yarnends and loops, the ends of w ich form upright rearwardlyfacing stops11a, and at the top and back it has at each sidean upstanding lug 12,each lug being spaced from stop 11a by a notch 12a. It also has anopen-top bearing hole 13 between end of the arm 7, and so that each maybeswung back into convenient position for dofi'- v ing the package, andso that, further, the

equipment comprising the carriers and packages will occup the minimum ofspace and not interfere with each other when either is moved from or toeither working or dofling position. Each carrier has a trunnion to entera bearing hole 13 and a spindle portionto en: ter the axial hole of thepackage A. It is here a piece of heavy but resilient wire having a thatwhen the packages are in wor body part 14, one end portion bent off inone direction to form the trunnion 15 and the other and considerablylonger end portionbent off in the other direction to form a stand ard orupright portion 16 and itself bent off and formed with a tapering return17 which constitutes what I have termed the spindle to enter the axialhole of package A which is assumed to have such hole too smallto admitthe tapering spindle without jamming, which thus gri s and holdsthepackage. An important eature of my invention is here to be noted: Thearrangement of the two carriers for any bracket is such (Figs. 1, 4 8and 9) king posi-' tion the spindle and trunnion of each carrier areatopposite sides of the upright 3, so that their body parts 14 lap eachother (or here intersect), thus producing a most compact arrangementwhile permitting each loaded carrier to be swung to dofling position(dotted lines Fig. 4) with ample clearance for dofling and withoutinterference with the other loaded carrier. Otherwise stated, in theworking position each pivoted carrier here crosses the correspondingupright 3 betweenits pivot and package or load carrying portions. In theworln'ng position of a carrier its body part is interposed between upright 3 and lug '12; when it is in dofiing position it is between lug 12and stop 11a, or engaged in notch 12a. To move it from either positionrequires simply sufficient force to cam it over the lug. Since thepivoting level of the two carriers is here the same the body part of onemay have a portion. thereof bent downward, as at 14a, Figs. 2, 5 and 6,to clear the corresponding portion of the other when they are in theircrossing relation-to each If the package is not a cone, as in Figs. 1 to4, with a large axial hole, but consists of windi gs on a spool or othercore B having a small ole, as the spools in Figs. 7 to 9, the bent-offportion 16 may have its bent-off ex- (0 tremity or. spindle plain, orwithout the return, as at 17 a in these latter figures.

With respect to a radius from its pivot at 13 each carrier has itspackage supporting portion or means 17 arranged to support the 76package with its axis crossing and substantially perpendicular to suchradius and the yarn package is arranged on said means so as to becrossed substantially midway of its length by said radius. Therefore,while each yarn package may stand in delivering position with its axisalined with'the yarn guiding means at the end of arm 7, in swinging 1from that. position the arc of travel of. the extreme point of theentire swinging structure is one of the shortest possible radius,whereby a greaternumher of such structures side 'by side can beaccommodated in the frame than would otherwise be possible.

The tension means (incidentally also a guiding means) hereih set forthfor example, and preferred, is essentially the same as that set forth inmy copending application Serial No. 525,600, filed March 27, 1931. Forthe present purpose it is suf'ncient to describe it 05 riefly asfollows: On the end of arm 7 is a plate 18 having a depending le 18a inwhich a spindle 19 is pivoted to roc toward and from the observer inFig. 2, being suitably limited to a short are of movement and normallyurged from the observer, as by gravity. On this spindle is a revolublepulley 20 sub ject to the braking action of a weighted nonrevoluble disk21 resting on the'pulley and pressing it against a non-revoluble support.22 on the spindle. The yarn .O extends from the package A (or B) to andaround the puliley in at least one completeturn and then toward theobserver (compare also with Fi 1). Draft on the yarn, if the pulley 1ssnubbed thereby, is opposed (here) by two .forces, i. e., the forcenormally holding the spindle and pulley from the observer in Fig. 2 andthe braking action exerted on the pulley. This snubbing is here effectedby a 115 light drag on the yarn between thepulley and package A (or B)produced by two superposed disks 23 confined in superposed relation toeach other by three pins 24, but not so that gravity acting on the topdisk will not be free to urge it toward the lower disk with consequentlya certain degree of pressure on 1 the yarn (which travels between themand is bent in an angle around the central pin) and thus creates thedrag. I

In Figs. 1 to' 8 one such tension (guiding) means serves two packages,and the spindles of the latter are arranged so that the axes of saidpackages converge toward such tension means, common to them. In Fig. 9the arm 130 7 has a cross-extension 25 carrying two such means, one foreach ackage, whose spindles are so arranged that t e axes of the twopackages are alined with the respective tension means.

When the creel is tends from one of supply to and around its tension(guiding means and then to and through the reed or equivalent (Fig. 1).The supplies may be superposed on each upright in any number (Fig. 3),those at any one level delivering their yarns in a horizontal sheet.That pack age of any supply which at a given time is delivering yarn hasits tail end (or the end first wound in forming the package) spliced, asat C by the attendant to the leading end (or end last wound on) of thecompanion package according to the well known custom. When the firstpackage is exhausted the yarn will'thus proceed to deliver from thesecond one without interruption, the attendant then replacing the firstpackage by a fresh one and splicing the tail end of the yarn of thesecond package to the leading end of the fresh package; and so on. Theattendants position for these purposes, it will be seen, is outside ofthe creel.

-Having thus fully described my invention what I claim is: 1. In acreel, the combination of support- .ing structure and a pair of yarnpackage carriers vpivoted therein on substantially parallel axes andlapping each other and each pivotally movable on 1ts pivoting axis, saidcarriers having means with the package axes extending in the samegeneral direction when the carriers lap each other.
